This place was decent, it’s the first place I stayed in Bangkok (for 2.5 months). The room is quite large and nice, with a small balcony!
The neighborhood is very quiet and very local Thai. I only saw 2 foreigners the whole time I was staying there. However, there is a 7-11 within close walking distance and a motorcycle taxi rank across the street from the store. There is also a pretty decent Italian restaurant/wine shop at the corner of Soi On Nut 17!
On the weekends there is a night market with a good variety of groceries and street food. There are also 5-6 small food stalls during the week/day.
Room has a mini fridge, a microwave, and an electric tea kettle. There is also a closet for clothing and a small table for eating or working.
Bathroom is all right, pretty standard for a budget place, although the faucet/tap seemed a little loose. It all worked very well though. AC was good.
Drawbacks: The bed is very hard, it is literally a box spring with no mattress so while this may be good for your back, it definitely took some getting used to for me. BTS (the sky train) is not close and you will need to either take a cab or a motorbike there. (I never did quite work out the shuttle system, if there is one) WiFi is intermittent, at least on my floor (3rd floor) so unless you have a good data plan/hotspot you will need to go somewhere to use.
Pluses: They let me keep my cat in the room with me. They also did not bother me, check in was very simple with their security guard after hours (late flight), checkout was also easy (just left the key). It was also really nice to sit on the balcony in the evening while I worked on my laptop. Yair was very helpful (reachable on Line app).
Overall this is an amazing deal, especially for 30+ days, and I very much recommend if you are looking for something on a budget!
